Our Gas Pressure Washer Buying Guide

As a homeowner, you likely take great pride in the curb appeal of your home – no matter whether you’ve owned your house for just a few months or for many years. After all, it’s your castle, the place where you and your family spend the majority of your time outside of work and school.

If you really want to make the exterior of your home sparkle, you’ve likely considered investing in a gas pressure washer to keep it spotless. From your driveway to your siding (and lots of places in between), a gas pressure washer can quickly and easily rinse away years of build-up and grime.

A gas pressure washer is one that uses gas instead of electricity for power. Since you don’t have to plug your gas pressure washer into an outlet, you can easily transport it anywhere you need to blast some dirt away — there’s no hassle of getting out an extension cord or trying to stay near an outlet.

Gas pressure washers won’t cause your electricity bill to spike, either. You’ll simply refill your gas pressure washer with gas from a gas pump, much like you would a gas lawnmower. They’re also extremely easy to use, once you’ve read through the instruction manual and got the hang of things. You’ll be powering through stubborn dirt on your fence, your gutters, your windows and other areas of your home or business in no time.

DWYM Fun Fact

To fully understand the awesome power (and danger) a gas pressure washer produces, it’s helpful to compare it to your standard garden hose. Case in point: the water pressure of your garden hose is somewhere in the neighborhood of about 50 pounds of pressure per square inch. Your gas pressure washer? Believe it or not, it’s closer to 1,000 to 4,000 pounds of pressure per square inch, which is a huge difference. That’s also why it’s super important to follow all the safety protocols in the user manual so that no one gets hurt. Always keep an eye on children when you own a pressure washer, even if you think it’s stored out of sight — you can never be too careful when it comes to that much pressure.

The Gas Pressure Washer Tips and Advice

  • Regular maintenance is critical for keeping your gas pressure washer working like new. You’ll want to follow all of the maintenance and cleaning processes listed in the user manual to ensure that your gas pressure washer has a long life without issues.
  • If you’re just getting started with your new gas pressure washer, consider testing it on a small, hidden patch of whatever surface you’re trying to clean. It can take a few tries to really get the hang of pressure washing, so this will give you a place to practice until you’re confident in your abilities.
  • There’s a difference in power among gas pressure washer models. Typically, you can separate them into broad categories: light-duty, medium-duty and heavy-duty. The power of a gas pressure washer will be labeled in pounds per square inch, typically written as “PSI.” In essence, this number tells you about your pressure washer’s ability to blast or strip dirt off of a surface.
  • In general, light-duty pressure washers have a PSI of up to 1900 and are good for light jobs around the house, like washing your car. A medium-duty pressure washer might have a PSI between 2000 and 2800, whereas a heavy-duty model typically has a PSI above 2800. The Ryobi 3000 PSI, for example, is incredibly powerful, thanks to its Honda GCV160 engine. Some models, such as the Generac OneWash 3100 PSI, allow you to adjust the pressure for varying jobs.
  • Another important metric to know before purchasing a gas pressure washer is its volume, which is labeled in gallons per minute, or “GPM.” This number is just as important as the pressure, as you need the flow of water to move the dirt and grime away from the surface you’re cleaning. With the Westinghouse WPX3200 Gas Pressure Washer model, for example, you’ll get 2.5 gallons per minute for volume.
  • Consider how important accessories are before purchasing a gas pressure washer. The Simpson Cleaning PS3228 PowerShot 3300 PSI Gas Pressure Washer, for instance, comes with five different nozzle tips that you can connect to its steel spray wand, which means it can easily switch between cleaning your RV, your driveway or your home’s siding.
  • If you’re looking to save a little bit of money, the SIMPSON Cleaning CM60912 2400 PSI Gas Pressure Washer offers the best value.
